Question

cells of other organisms

1. observe organism 5, mayorella.

identify which organelles are visible in this sample.
visible organelles: sample 2
nucleus: a
chloroplasts: b
mitochondria: c
cell membrane: d
cell wall: e

Explanation:

Mayorella is an amoeba, a heterotrophic protist (animal-like). As a non-photosynthetic, non-plant eukaryote:

1. The nucleus is a large, distinct organelle visible at 1000x magnification.
2. It lacks chloroplasts (does not photosynthesize).
3. Mitochondria are too small to see at this magnification without special staining.
4. It has a cell membrane (defines its shape) but no rigid cell wall.

Answer:

A. Nucleus: Visible
B. Chloroplasts: Not Visible
C. Mitochondria: Not Visible
D. Cell Membrane: Visible
E. Cell Wall: Not Visible
